🌌 100 Amazing Facts About Uranus

Uranus is the seventh planet from the Sun.
It’s classified as an ice giant along with Neptune.
Uranus was discovered by Sir William Herschel in 1781.
It is the first planet discovered using a telescope.
Uranus is named after the Greek god of the sky.
It has a blue-green color due to methane in its atmosphere.
Uranus rotates on its side, tilted about 98 degrees.
Its unusual tilt causes extreme seasons lasting over 20 years.
One Uranian year equals about 84 Earth years.
Its day lasts around 17 hours and 14 minutes.
Uranus is the third largest planet in our solar system.
It has a diameter of about 50,724 kilometers.
Uranus has 13 known rings.
The rings are mostly made of dark particles and ice.
Uranus has 27 known moons.
Most moons are named after Shakespeare and Alexander Pope characters.
Titania is its largest moon.
Oberon is the second largest moon.
The temperature on Uranus can drop to -224°C, making it the coldest planet in the solar system.
Its atmosphere contains hydrogen, helium, and methane.
Uranus has a very weak internal heat source.
The planet’s magnetic field is tilted 59 degrees from its axis.
Uranus was first thought to be a star before its discovery as a planet.
The Voyager 2 spacecraft is the only one to visit Uranus (1986).
Uranus has faint auroras caused by solar winds.
The planet’s core may be rocky and icy.
The atmosphere has layers of clouds made of water, ammonia, and methane.
Its storms can reach speeds of 900 km/h.
The planet has an average distance of 2.9 billion km from the Sun.
Light from the Sun takes about 2 hours and 40 minutes to reach Uranus.
The planet’s gravity is 0.89 times that of Earth.
You would weigh slightly less on Uranus than on Earth.
It takes Uranus 17 hours to spin once on its axis.
The methane in its atmosphere absorbs red light, giving it its blue-green hue.
Its moons were discovered between 1787 and 2003.
Miranda, one of its moons, has the tallest cliff in the solar system.
That cliff, Verona Rupes, is about 20 km high.
Uranus has been visited only once by humans (via spacecraft).
The planet was almost named “George’s Star” after King George III.
Uranus’s rings were discovered in 1977.
Some of the rings are very thin and dark.
Its magnetic field is not centered like Earth’s.
The tilt of its magnetic field makes its auroras unpredictable.
Uranus likely has a rocky core about the size of Earth.
The outer atmosphere has strong winds and storms.
The ice in Uranus is not the kind you find in your freezer—it’s hot and dense.
Uranus is visible to the naked eye under dark skies.
The planet’s apparent magnitude is around +5.8.
The name Uranus follows the tradition of naming planets after gods.
It is the only planet whose name comes directly from Greek mythology.
Uranus has a pale cyan color in telescope images.
Its seasons are the most extreme in the solar system.
During summer, one pole is in constant sunlight for 42 years.
During winter, the other pole is in complete darkness for 42 years.
Scientists believe Uranus was knocked on its side by a giant collision.
Uranus’s moons are irregularly shaped except for Titania and Oberon.
Many moons have icy surfaces with deep canyons.
Uranus has a very low density compared to Earth.
Its average density is about 1.27 g/cm³.
The atmosphere may contain hydrogen sulfide, giving it a rotten egg smell.
Uranus emits less heat than it absorbs from the Sun.
The winds can blow opposite to the planet’s rotation.
The upper atmosphere has haze layers.
The haze makes the planet look smoother in images.
Uranus has no solid surface.
It transitions from gas to a slushy icy layer as you go deeper.
Voyager 2 discovered 10 new moons during its flyby.
Its rings are younger than the planet itself.
Uranus’s magnetic field reverses direction daily.
The tilt makes its magnetic poles not aligned with its geographic poles.
Some moons may have subsurface oceans.
Titania might have a thin atmosphere.
Uranus has been studied using the Hubble Space Telescope.
Earth-based telescopes continue to monitor Uranus’s weather.
Bright clouds occasionally appear in its atmosphere.
These clouds are made of methane ice crystals.
Uranus’s rotation is retrograde, like Venus’s.
Retrograde means it spins in the opposite direction to most planets.
Uranus’s core may be partially liquid.
Its ring particles are smaller than those of Saturn.
The inner rings are more densely packed than the outer ones.
Some moons orbit within the rings.
Cordelia and Ophelia act as shepherd moons.
The planet was the first to be discovered in modern history.
Before Uranus, all planets were known since ancient times.
Galileo may have observed Uranus in 1612 but thought it was a star.
It wasn’t recognized as a planet until 1781.
The temperature deep inside Uranus may reach 4,700°C.
Its interior is mostly water, ammonia, and methane ices.
Storms on Uranus are rare but massive.
In 2014, astronomers saw huge bright spots in its atmosphere.
It’s one of the least explored planets in our solar system.
NASA plans possible future missions to Uranus.
The James Webb Space Telescope can observe Uranus in detail.
Uranus’s moons may hold clues about the early solar system.
Its axis tilt is the most extreme of any planet.
The tilt may cause chaotic weather patterns.
Uranus’s position changes slowly in our sky.
The best time to see Uranus is during opposition.
Opposition happens about once every year.
Uranus marks the boundary between the inner and outer planets.
It’s four times wider than Earth.
Its mass is about 14.5 times that of Earth.
The name Uranus is pronounced “YOOR-uh-nuhs” or “YOOR-uh-nohs” in astronomy circles.

From its dramatic tilt to its icy winds, Uranus remains one of the most intriguing worlds in our solar system. These 100 facts are just the beginning—future missions and telescopic studies will likely reveal even more secrets about this distant ice giant.
